The Importance of Routine Fluid Analysis for Transformers
Insulating fluid is the first place a developing problem with a transformer shows up. As utilities work to stretch aging transformer fleets further while managing tighter budgets, routine fluid analysis has become one of the simplest, most reliable ways to catch trouble early and keep equipment in service longer. At TJ|H2b, insulating fluid analysis is […]
Transformer Testing Decision Guide: When, Why & How to Test Insulating Fluid
Do you need transformer testing right now, and if so, which test? This guide is designed to answer the signs, the tests that match, where to get transformer testing, and what to do with the results. Do Transformer Testing if Any of These Signs Apply to You If any of the following is true, you […]
The Power of Dissolved Gas Analysis: DGA Testing
Long before a fault becomes visible in a transformer, it leaves a trace in the insulating oil. Things like dissolved gases are produced by thermal and electrical stress inside the unit. Catching those traces early is one of the most cost-effective ways to avoid an unplanned outage. That’s the job of Dissolved Gas Analysis (DGA) […]
Why Laboratory Testing Remains Irreplaceable in the Smart Grid Era
The modern power grid is more robust than at any point in history. Utilities are deploying IoT sensors, online dissolved gas monitors, SCADA integrations, and AI-driven analytics platforms at an accelerating pace. This is good news for grid reliability. But a misconception is gaining momentum in the industry: that continuous digital monitoring is making laboratory […]
Common Misconceptions About Transformer Testing
Despite decades of standardized testing protocols and robust diagnostic science, a surprising number of misconceptions persist among plant engineers, maintenance teams, and asset managers regarding industrial transformer testing. Unfortunately, these myths can lead to under-testing, misinterpreted results, deferred maintenance, and, in the worst cases, catastrophic and preventable failures. At TJ|H2b Analytical Services, we have spent […]
Understanding High Voltage Circuit Breakers
A high voltage circuit breaker is a switching device used in power systems to interrupt the flow of electricity when abnormal conditions occur, such as short circuits, overloads, or ground faults. By rapidly opening the circuit, the breaker isolates the faulty section of the network, protecting equipment, preventing fires, and maintaining system stability. To safely […]
Transformer Insulation Innovation: Why Advanced Materials Still Depend on Oil Diagnostics
As utilities face increasing grid load demands, aging infrastructure, and the rapid expansion of renewable energy, transformer reliability has become more important than ever. One of the most significant factors affecting transformer reliability is insulation performance. Traditional transformer insulation systems (typically composed of cellulose paper and insulating oil) have served the industry for decades. However, […]
How to Correctly Take an Oil Sample from a Transformer
Modern high-voltage equipment rarely fails without warning. Long before a transformer, regulator, load tap changer (LTC), or breaker experiences a catastrophic event, microscopic indicators begin developing inside the insulating fluid: Dissolved gases form, moisture increases, acids develop, and metal particles circulate. But none of that data matters if the oil sample is compromised. Improper sampling […]
“What’s in Your Oil®?” How Microscopic Evidence Reveals Failure in Electrical Equipment
Modern electrical equipment rarely fails without warning. Long before a transformer, regulator, or load tap changer (LTC) experiences a catastrophic event, microscopic evidence begins to accumulate inside the insulating oil. This evidence provides critical insight into developing failures. Microscopy and Forensic Analyses take a deeper look at “What’s in Your Oil®”. Microscopy analysis transforms oil […]
Dielectric Breakdown Voltage Testing Methods
Dielectric breakdown voltage testing is a critical process in assessing the electrical insulation properties of materials used in various industrial applications. For utilities navigating increasing load demands, renewable integration, and aging infrastructure, insulation diagnostics have never been more critical. At TJ|H2b Analytical Services, dielectric breakdown voltage (DBV) testing remains one of the foundational measurements we […]
What’s The Difference Between Routine Insulating Fluid Analysis and Diagnostic Analysis?
To get straight to the point: not all insulating fluid analysis serves the same purpose. Understanding the distinction between routine oil analysis and diagnostic analysis helps utilities make smarter maintenance decisions, avoid unnecessary downtime, and respond effectively to early warning signs. At TJ|H2b Analytical Services, we emphasize that both types of analysis are essential parts […]
Ensuring Gas-Insulated Breaker Integrity with BGA® Testing
When a gas-insulated breaker (GCB) or gas-insulated switchgear (GIS) fails, the risks extend far beyond lost equipment. Given the critical role these assets play in transmission and substation reliability, Condition-Based Maintenance (CBM) supported by laboratory diagnostics is essential. At TJ|H2b Analytical Services, our Breaker Gas Analysis, BGA®, is a proprietary diagnostic program designed to deliver […]
